S is a sprocket-wheel connected with the pinion S, and S is a sprocket-chain passing around said sprocket-wheel and extending across the front of the frame and around a corresponding sprocket-wheel S at the outer end of a lateral extension of said frame. This lateral extension is preferably formed by a tension of the shelf A slightly in rear thereof by the brackets T. This holder is adapted to receive a pile of slats in vertical series, the lower slat resting on a slotted bottom plate and a slot being formed in the end of the holder of suiiicient width to allow this lower slat to therethrough.

Beneath the holder T is formed a track or guide-rail T preferably an angle-bar, which extends some distance over the main frame.

T is a head or carriage slidingly secured on the rail T to which is secured the slatcarrier or what I shall term the shuttle T*. This shuttle comprises two parallel bars cl, spaced a distance apart slightly greater than the width of the slats and being also of slightly-greater thickness thanthe slats.- At

n and o are tubes secured to the plug 7r; in line with the passagesland m and extending to the opposite end of the twister.

V are reels at the rear end of the frame adapted to carry the coils of main wires from which the wires extend through the tubes n and the twisters.

W are small ,reels or spools carrying the binding-wires, which are preferably sleeved upon the rear end of the twister-tubes and from which the wires are led into the tubes 0 of the twisters.

The'parts being constructed and arranged as shown and described, the operation of the machine is as follows: A pile of slat-s is first placed in the holder T and coils of wireon the reels V and spools W. The machine may then be set in operation, motion being imparted to the wheel I and through the medium of the clutch-sleeve 1 to the pulley 1 From the pulley 1 motion is transmitted to the belts N and N, which in the initial position of the belt-shifters are respectively in engagement with the loose pulley M and the tight pulley M on the shaft M. The belt N will thus impart rotary motion to the shaft M in one direction, which through the medium of the worm R and worm-wheel R will rotate the shaft E, causing the pinions E to travel backward on the racks E from their initial position at the forward ends of said racks and carrying with them the shaft E, the bearing (3 thereon, and the twisters B. At the same time motion from the shaft M is transmitted through the medium of the gear-wheels M and S to the sprocket wheel S and the sprocket-chain S causing the latter to travel in a direction to carry the lug S inward. The lug S engageswith the dog 6 and causes the head T to slide along the track T carrying with it the shuttle T and a slat therein which is pushed out of the holder by the dogf. Before the shaft E and twisters B have reached their rear position the shuttle has carried the slat between the main and binding wires, which extend forward from the twisters and through the slotted guides U, into-thelposition opposite the twisters, where it is to be deposited, at which point in the operation the releasing-arm of the doge will strike against the cam e and disengage said dog from the lug 8. During the rearward movement of the shaft E the double bearing-bracket R will cause the worm R to slide along the shaft M, while its feathered engagement therewith compels it to rotate with said shaft. Before the shaft E has com pletedits rearward movement it will strike against the arm Q on the rod Q pushing said rod backward and causing the collar Q to carry the sliding standard Q and rod Q with it and placing a tension on the spring Q the rear end of which presses against the standard Q The standard Q is, however, temporarily held from movement by the en gagement of the hooked arm of the bell-crank lever P with the detent Q but in the further movement of the shaft E it will strike against the upper end of said bell-crank lever and turn it sufficiently to disengagethe hook from the detent. The spring Q will then force the frame Q and rod Q backward by a quick movement, which is communicated to the lever P, which in turn will slide the bar 0 forward, carrying with it the grooved cams O and 0 The movement of these cams will rock the arms N and N of the belt-shifters N and N and cause them to shift the belt N from the loose pulley M to the tight pulley M and the belt N from the tight pulley M to the loose pulley M thus causing a reversal in the movement of' the shaft M. (See Fig. 3.) The shaft E in its rearward movement will also strike against the arm K on the rod K, which will draw the arm K backward and rock the shaft K. This will rock the arm K forward, carrying the roll K in front of the disk J and allowing it to drop by gravity down until the stop K on the rod K rests upon the upper end of the tubular arm K. The reverse movement of the shaft M will cause the shaft R and twisters B to travel forward and the sprocket-chain S to travel in the reverse dimotion, the lug S engaging with the dog 0 and carrying the sliding head T and shuttle T outward. The slat which is in the shuttle is, however, not carried out again therewith, as the springs 71, will press it against the slotted guide U, and as there are three pairs of these springs-and guides two of them will always be holding the slat while the top and bottom plates 61 and d of the shuttle-point are drawnby the third guide and spring. In passing outward the bars 61 of the shuttle will pass upon opposite sides of the slat-holder '1, while the dogf will pass through the slot in the bottom plate. The shuttle will be fully withdrawn before the twisters have reached the position of the slat, and when withdrawn the releasing-arm of the dog e will strike against the cam e and disengage said dog from the lug S. The further forward movement of the twisters will carry the slat forward in the slotted guides U and under the springs t', which will hold it during the operation of twisting. In the forward movement of the shaft E it will strike against the arm Q which will move the rod Q forward, the collar Q thereon carrying the sliding standard Q and sliding bar Q with it and compressing the spring Q against the collar Q on the rod Q The latter is held from movement by the detent Q on the standard Q which became engaged with the hooked arm L in the rearward movement'of said standard. The movement of the bar Q will through the medium of the lever P and sliding bar 0 imparta partial movement to the cams O and 0 which are so shaped that the shifter N alone will be operated by this partial movement. This will shift the belt N from the tight pulley M to the loose pulley and stop the rotation of the shaft M. Before the forward movement of the shaft E is stopped, however, it will strike against the arm K and rock the shaft K, which will rock the arm K backward and cause the roll K to push back the disk J, engaging the clutch-sleeve I, with the clutch-hub of the wheel I. This will start the rotation of the shaft H, which is communicated through the sprocket-andchain connection to the twisters B, causing them to twist the wires in rear of the slat. As the shaftH rotates the disk J will be turned vice therefor.

therewith, causing the roll K to travel outward in the spiral groove J until it reaches the periphery of the disk, when a suitable returning device,- such as the weighted lever X, will push the disk forward, disengaging the clutch members and stopping the rotation of the shaft. Simultaneously with the releasing of the clutch the hooked arm I will release the detent Q, on the frame Q this be ing caused by the raising of the rod K which rocks the rock-arm L and rock-shaft L, to which the arm L is secured. Upon the re leasing of the detent the spring Q will move the frame Q and with it the rod Q, which through the connections before described will complete the movement of the cams O and 0 causing the belt-shifter N to shift the belt N from the loose pulley M to the tight pulley M and start the rotation of the shaft M again in the reverse direction.

From the general description of the operation of the machine as above given it will be seen that its action is entirely automatic, the only attention required being to replenish the pile of slats in the holder as often as necessary.

I wish now to call attention more specifically to certain features of construction and the operation of certain parts as yet notfully described.

First, the construction of the holder for each of the binding-wires and the tension de- The spool W is sleeved upon the rear end of the sleeve G free to rotate thereon. said sleeve G in rear of the spool, the opposite arms of which extend outward beyond the flanges of the spool. is a curved tube extending around from tube 0 to one end of the cross-bar IV. is a pin on the other end of said cross-bar, on which is pivotally secured a bifurcated lever W extending on opposite sides of the flange of the spool W. One side of this lever is adapted to rest upon the wire on the spool and is compelled to travel inward as the wire is drawn off from the spool by the spring W which is so arranged as to exerta constant inward pull upon said lever. W is an adjustable friction device on the outer arm of the lever adapted to press against the flange of the spool and place tension upon the wire. In the operation of the machine this device will place a perfectly uniform tension upon the bindingwire, as the friction device W is always applied to the spool at the same distance from the axis thereof as the wire leading olf therefrom, and this will not decrease the tension as the amount of wire on the spool diminishes. In order to provide means for readily winding the spool, I place upon each a bolt or catch IV adapted to be engaged with a notch in a collar 0, which is fast upon the sleeve G in rear of the bearing D. This will permit of driving the spool with the sprocket G and sleeve G and winding the bindingwire on the spool W. In order to allow this 'W is a bar centrally connected to' winding to be done independently on each of the spools, I provide means for preventing the rotation of the other spools by loosening the sprocket G upon the sleeves G. This may be done by providing a collar G at the forward end of the sleeve G and a clampingplate G secured to the sprockets by the screws G and adapted to either clamp said sprocketto the collar G on the sleeve G or when the screws are loosened to permit of its freely re volving thereon.

I wish also to call attention to the means employed in my machine for engaging the slat last inserted with the holding-clamps and pushing the woven fabric forward. In former constructions of machines this has been done by the twisters pressing directly against the edge of the slat and forcing it into the holder. The effect of this is that the slat is generally marred when the twisters first begin to rotate. In my construction I obviate this difficulty by placing 'pushcrs on the bearing 0, which extend slightly beyond the forward end of the twisters and are adapted to bear against the slat. These pushers are preferably in the form of sleeves G, surrounding that portion of each twister which extends beyond the bearing 0, which sleeves are secured to hubs on said bearings. cured to the twisters on opposite sides of the bearing 0 to prevent end movement in said bearings.

Finally, I will describe more in detail the means for drawing the slats out of the holder and engaging them with the shuttle. Just before the shuttle reaches its inmost position the sliding head T will strike against the sliding head T moving said head,and through the connecting-rod 9 also sliding inward the head T which carries the dog f. As the dog is adapted to engage with the lowest slat in the holder, it will push'said slot before it, so that when the shuttle again moves outward the end of the slat will be projecting slightly beyond the holder and free to engage with the socket in the point of the shuttle. The dog f will then engage with the rear end of said slat and when the shuttle again moves inward will carry the slat in the manner before described.

. As the slats may vary slightly in length, I provide means for keeping them in line at the inner edge of the fabric. This consists of a stop y, against which the end of the slat may strike, and to prevent the dog ffrom doing injury in case the slat strikes said stop before the head T has completed its inward movement I secure said dog to said head by the yielding connection, such as the sprin \Vhat I claim as my invention is- 1 In a wire-and-slat-weaving machine, the combination with the work-holder and the rotary twisters adapted to be reciprocated to ward or from said holder, of mechanism for feeding the slat endwise between said worle holder and twisters in the retracted position of the latter.
